This invention relates to a carrier for a braiding machine; and has for one of its objects the elimination of pawl and tooth arrangements for controlling the let-off of the package.

Another object of the invention is the provision of a means for nipping the yarn to control the let-off of the yarn from the package rather than the customary manner of controlling the support for the yarn.

Another object of the invention is the provision of a braider carrier which will accommodate a package of a larger size than packages usually accommodated.

Another object of the invention is the provision of a carrier which will have the stop for throwing off the stop lever of the braiding machine separate from the take-up means for the yarn.

Another object of the invention is the provision of a carrier with a single guide post with such resilient means as is utilized for the takeup housed within the guide post.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

It is usual in braider carriers to provide a pawl on the carrier and a ratchet or toothed base on the package with which the pawl engages to control the let-off of the yarn on the package; and in order to eliminate this mechanism and simplify the control, I have provided a nip for the yarn which will be intermittently released by a usual take-up mechanism so that the pack- 10 vantageous results may be accomplished:

With reference to the drawings, 55 designates the base of the braider carrier provided with flanges l6 and l! on either side of a web l8 which is guided through the race-way plate of the braiding machine. Upwardly from this base there extends a boss l9 from which there extends a package spindle 20. A disk 2i with a depressed center portion 22 is supported on the shoulder 23 formed between the boss l9 and the spindle 20 for the reception of the pasteboard cop 24 of the yarn package which extends below the package 25 of yarn when the'same rests upon the upper surface of the disk 2l. Suitable resilient bowed rods 28 are located along the spindle and spring outwardly when relieved from pressure, but when the cop is mounted on the spindle serve to friction the cop sulficiently so as to retard rotation of the package as the yarn 21 is drawn therefrom. A guide standard 30 is supported in a recess 3| in the protuberance 32 of the base and has slidably mounted thereon a stop 33 having an opening 34 to receive the guide standard 30, there being an arm 35 bent over as at 3B and provided with an opening 31,

for also receiving this guide standard to direct the vertical movement of the stop along the standard. Fingers 38 on the stop extend inwardly and are positioned on either side of a stud 39 threaded into the base as at 40 and provided with a head ll with which the fingers engage to limit the upward movement of the stop and prevent it from rising beyond the disk 2! which supports the package.

The yarn take-up is designated generally 42 and comprises a body portion 43 with a ring 44 at the lower end of the body extending at right angles to the body and encircling the guide standard 30 while at its upper end there is provided an encircling ring 45 also extending about the guide standard 30. Between these two guides an arm 45 extends laterally from the body and is provided with a hook 4T beneath which the yarn passes, while there is a projection 48 extending upwardly beyond any of the other parts of the take-up for engaging and releasing the nipping mechanism which will be presently described.

The nipping mechanism comprises a collar 49 for encircling the guide standard 30 and bound in adjusted position thereon by means of the ears 50 and 5| with a bolt 52 extending through the ear 5| and into the threaded opening 53 in the ear 50. This collar has a bracket 54 extending therefrom with a bent-up finger 55 forming an eye 55 through which the yarn is guided. A resilient member 51 is secured by riveting or welding as at 58 to the bracket 54 and affords a resilient means to clamp the yarn between it and the bracket as it is led therethrough. This resilient member 57 extends outwardly into the path of movement of the projection 48 on the take-up so that when this take-up engages the resilient member 57 it lifts the same to release any yarn held between the bracket and this resilient member, this release being illustrated in Fig. 3.

Yarn from the package 25 is drawn upwardly over the disk l5 having a stem 16 entering the pasteboard cop tube 24 and forming a guide for the yarn and thence through the opening 60 in the arm BI, and then extends downwardly through the opening 63 in this arm 5| to pass through the eye 55 and beneath the resilient member 57, thence downwardly beneath the hook 47 and upwardly through the pigtail guide 65 supported at the upper end of the guide standard and thence to the braiding point. This guide 55 may be formed on the end of the pin 62 for pivotally supporting the arm 6| so that it may be rocked from working position to the position shown in dotted lines in Fig. 1 for removal and replacing of the package from the spindle 30. This hinging thus enables the guide to be located closer to the bobbin.

A spring 65 housed within the tubular guide standard engages a hook 67 secured to the body of the yarn take-up at its upper end while its lower end engages a hook 68 secured to the arm.

35 of the stop. The yarn thus lifts the takeup and through the spring the take-up lifts the stop, thus causing the stop to be lifted upwardly by reason of the spring, the take-up being drawn dovmwardly. As yarn is needed at the braiding point the yarn will cause the take-up to be lifted until its projection 48 engages the resilient member 5'! to release the nip at this point on the yarn, whereupon more yarn will be drawn through the nip mechanism from the package, the same turning if desired and the take-up member moving downwardly under action of its spring to take up any slack in the yarn, the yarn, however, acting to support the stop through the spring mechanism provided.

Should, however, the yarn break or fail by reason of exhaustion the take-up mechanism will then drop suddenly into engagement with the stop sliding it down the guide standard into a position which will throw off the lever of the braiding machine as the carrier moves into a position to engage the part which it throws for this purpose. The protuberance 32 has slightly inclined sides 11 while the ends of the stop have a corresponding incline 18 to fit these sides 1'! and thus support the stop in the shock which it receives in actuating the stop lever of the braiding machine and relieving any strain which might otherwise occur on the pin 39.

In some instances instead of providing the nip mechanism closely adjacent the top of the package I may provide a bracket arm 10, as shown in Fig. 10, extending from the collar 49 downwardly with the arm directed outwardly as at H and the guide mechanism 55 and resilient member 51 provided as heretofore. In this case instead of drawing the yarn from the top of the package through a guide arm the spindle 20 is of a length to extend through the package and I provide an equalizing bail 12 over which the yarn is drawn from the package to this guide eye 55 and thence beneath the hook 41 and then upwardly through the pigtail guide T3 at the upper end of the guide standard and thence to the braiding point. This pigtail guide is mounted in any suitable manner, such for instance as on a screw 69 threaded into the end of the standard. The take-up mechanism and stop in this modified form of construction are the same as that previously described as are the other parts of the mechanism heretofore previously described.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.
